Nisland, SD population, income and ZIP codes

Nisland town is a very small community in South Dakota, with 167 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #254 of 485 ranked by population — larger than 47% of them. The median age here is 31.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Nisland town earn a median of $29,444 a year, 62.5% below the national figure of $78,538 and 55% below the $65,500 median for the 79 South Dakota cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 24% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Nisland town is valued at $75,500, 75.1% below the national figure and 61% below the $192,800 peer median, while median gross rent runs $950 a month, 32.4% below the national figure, or roughly $11,400 across a full year. A household on the local median income would put about 38.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 67.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Nisland town is the unusual combination of expensive to rent and cheap to buy: rent takes 38.7% of median income while homes cost only 2.6× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price. With 167 residents, a handful of survey responses moves every median on this page. Compare Nisland town against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
